« on: Apr 13, 2010, 06:29:53 PM »
just had to put a new dizzy in the 22re 1989 4runner, the timing seems to be dead on but now it wont downshift, i am going to double check the timing. seems to have good power when you ease into the thottle but if you flloor it, it wont downshift and does not seem to have alot of power. is my timing off still. the sun is shining and i need some top off driving. thanks

Check your TPS; the shift points are determined by it.
